Polyester fabric is woven from polyester filament, with bright appearance and smooth feel, that is, polyester taffeta. Polyester taffeta is suitable for umbrellas, car covers, sleeping bags, and tents.
Pongee fabric is commonly known as rainproof cloth and can also be called "coated nylon spinning". Its cloth surface is flat and smooth, light in texture but strong in wear resistance, good in elasticity and gloss, non-shrinking, easy to wash, quick-drying, and feels good.
Polyester taffeta and pongee are both polyester fabrics. But polyester taffeta is the lining; pongee is the fabric; polyester taffeta feels harder than pongee. Polyester taffeta is a full-length yarn, and at least one of the pongee warp and weft is low-elastic yarn.
